FWIW, I quad amp and use both fuses and a cap to protect the ribbons.

I do NOT use tube amps so I can't speak to their unique properties/considerations.

When you design your ribbon XO, you will have to take into account both the slope and phase rotation caused by the cap you select in addition to your DEQX XO, should you chose to use one.

I designed a FIR ribbon XO that includes a filter which electronically erases the slope and phase rotation of the cap, so when playing, the cap is essentially out of the circuit leaving just the digital XO. This guarantees the Mid and Ribbon XO's ideally sum without the cap tainting the XO region.
